Regulating Stablecoins as Money: A Framework for Trust, Competition, and Financial Stability

Stablecoins are best understood as a form of emerging monetary infrastructure, connecting reserve assets, banks, payments, wallets, capital markets, and settlement networks.

I. Introduction: Stablecoins Have Become a Question of Institutional Design

Stablecoins have moved beyond the boundaries of a specialized cryptoasset market. They are increasingly being considered as instruments for payments, cross-border transfers, trading settlement, tokenized financial markets, and, in some cases, everyday stores of monetary value. This evolution changes the nature of the policy question.

The central issue is no longer whether privately issued digital instruments can maintain a stable value. A number already do so for extended periods under ordinary market conditions. The more consequential question is whether they can perform monetary functions reliably when conditions become less ordinary—during periods of market stress, rapid redemption, operational disruption, intermediary failure, or declining confidence.

Money is ultimately an institutional arrangement as much as a financial asset. Its usefulness depends on confidence that one unit received today will remain usable tomorrow, that settlement will be recognized, that claims can be redeemed when promised, and that failures within the surrounding infrastructure will not arbitrarily transfer losses to users.

Stablecoins therefore raise a broader question about the design of digital money.

They can offer meaningful advantages. Transfers may occur continuously rather than within traditional banking hours. Settlement can be integrated directly into digital platforms. Cross-border payments may require fewer intermediaries. Programmability can allow financial transactions, commercial payments, and asset transfers to interact within the same technological environment. Competition from new infrastructure may also place pressure on existing payment systems to improve.

Yet the monetary promise embedded in a stablecoin creates obligations that technological innovation alone cannot resolve. A digital token may move across a blockchain in seconds, but the assets supporting it still have to exist somewhere. Someone must control those assets. Someone must honor redemption. Someone must maintain the operational system. Someone must bear losses when arrangements fail.

Good regulation therefore has to preserve two objectives simultaneously: protecting the properties that allow a stablecoin to function as trustworthy money while retaining enough flexibility for technological and institutional competition.

The most useful regulatory framework begins by separating the different risks rather than attempting to force the entire stablecoin ecosystem into a single traditional category.

II. What Is Being Regulated: A Digital Token, a Financial Claim, or Money?

Stablecoins are difficult to regulate partly because they combine features that historically belonged to different financial institutions.

A fiat-backed stablecoin may resemble a narrow bank liability because the issuer accepts money and creates a redeemable monetary claim. It may resemble a money-market instrument because its reserves are often invested in highly liquid, short-duration assets. It may function as a payment instrument because users transfer it in exchange for goods, services, or other financial assets. Its digital architecture may also allow it to behave like a bearer instrument that can move directly between users without requiring the issuer to update a conventional account ledger for every transaction.

None of these analogies is complete.

This matters because legal classifications often determine the regulatory framework. Banking regulation addresses one set of risks. Securities regulation addresses another. Payment regulation focuses on operational reliability, settlement and consumer protection. Asset-management regulation concentrates on portfolio composition, disclosure and custody.

Stablecoins cross these boundaries.

The more useful starting point is economic function. Technology determines how an instrument operates, but it does not by itself determine what the instrument does within the economy.

A token may technically qualify as a cryptoasset while economically functioning much more like money than an investment product. Conversely, a digital asset marketed as stable may contain investment characteristics that make monetary treatment inappropriate.

This distinction leads to one of the most important principles for regulatory design: the monetary claim and the infrastructure used to transfer that claim should be analyzed separately.

The first concerns the promise made to the holder. What exactly does ownership represent? Who owes the holder money? At what value can the claim be redeemed? What assets support that obligation? What happens during insolvency?

The second concerns the system through which the claim circulates. Who provides wallets and custody? How are transfers validated? When is settlement final? What happens if an intermediary, network, smart contract, or technological service provider fails?

Treating these questions separately makes it possible to regulate the economic risks more precisely without assuming that every component of the system must resemble a bank.

III. One Stablecoin, Several Economic Functions

A further difficulty is that the same stablecoin can perform different economic functions for different users.

Within cryptoasset markets, stablecoins have traditionally served as cash-like settlement instruments. Traders use them to move between positions, exchanges use them for liquidity, and decentralized applications use them as a common unit of account.

In cross-border commerce, the function may be quite different. A stablecoin can provide an alternative transfer mechanism between businesses, individuals, payment companies and financial institutions. The economic value in this context comes less from exposure to digital assets than from the possibility of reducing settlement time, intermediary layers and operational friction.

A third use is emerging in tokenized financial markets. If securities, funds, deposits, collateral or other financial claims increasingly exist on programmable infrastructure, market participants will require a reliable settlement asset that can operate within the same environment. Stablecoins are one candidate for that role.

A fourth use involves retail payments and stored value. If households and businesses begin to hold stablecoins as substitutes for bank deposits or payment balances, the policy implications become broader because the instruments begin to participate directly in the monetary system.

These uses create different risk profiles.

A stablecoin primarily used by sophisticated traders inside a digital-asset marketplace raises significant market-integrity and operational questions. A stablecoin used by households for savings raises stronger consumer-protection and redemption concerns. A stablecoin embedded in securities settlement may create financial-market infrastructure risks. A stablecoin widely used for cross-border payments raises questions involving sanctions, financial crime, foreign-exchange exposure and monetary sovereignty.

This suggests that regulatory intensity should follow function, scale and interconnectedness.

A framework based entirely on technological labels is likely to regulate some activities too heavily and others too lightly. Two identical tokens may require different safeguards when used in materially different contexts.

The objective should therefore be functional consistency: comparable economic risks should receive comparable regulatory treatment even when the technological architecture differs.

A stablecoin is simultaneously a monetary claim, a reserve-backed liability, a payment instrument, and a digital settlement asset; regulation should therefore follow economic function, scale, and interconnectedness.

IV. The First Line of Defense: Reserves, Redemption, and the Meaning of “Stable”

The starting point for any stablecoin designed to maintain parity with sovereign money is the credibility of the monetary promise.

Stability is not created by naming an instrument a stablecoin. Nor is it created by maintaining parity during periods of calm. The meaningful test is whether holders can redeem at the promised value when demand for redemption rises sharply.

This places reserve design at the center of regulation.

Reserve quality matters because an issuer that promises redemption at par cannot safely support that promise with assets whose value may decline substantially at precisely the moment liquidity is needed. High-quality, short-duration assets generally reduce that risk.

Liquidity is equally important. Solvency and liquidity are related but distinct. An issuer may own assets whose total value exceeds its liabilities and still experience severe difficulty if those assets cannot be converted into cash fast enough to meet redemption requests.

This is a familiar problem in finance. A claim that can be redeemed immediately should not be supported primarily by assets that can be liquidated only slowly or at uncertain prices.

Legal segregation provides another layer of protection. Stablecoin reserves should be insulated, to the greatest extent practicable, from unrelated claims arising from the issuer's operating business. If users believe that each token is backed by identifiable reserve assets, those assets should not become indistinguishable from the general estate of a failed company.

Transparency then allows both markets and supervisors to evaluate whether the promise is credible. Useful disclosure should explain reserve composition, maturity, concentration, custody arrangements and outstanding liabilities. Transparency cannot eliminate risk, but opacity can make confidence fragile.

The final element is redemption certainty.

A stablecoin may trade near par in secondary markets without providing every holder with a direct legal right to redeem against the issuer. That distinction becomes especially important in stress. Market liquidity can disappear precisely when users most need an exit.

Regulation should therefore pay close attention to who possesses redemption rights, through which channels, at what cost, and under what conditions those rights may be suspended.

The concept of a stablecoin is ultimately meaningful only when the underlying legal and financial arrangements make stability credible.

The credibility of a stablecoin depends on reserve quality, liquidity, legal segregation, transparency, and a clear right to redeem at par, especially under stress.

V. The Second Line of Defense: Custody, Payments, and Operational Trust

A strong reserve structure is necessary, but it is not sufficient.

Money must also move safely.

A fully backed stablecoin can still fail users if wallets are compromised, custodians become insolvent, networks become unavailable, smart contracts malfunction, redemption channels stop operating, or the legal consequences of settlement remain uncertain.

This is where discussions of decentralization can become misleading.

Financial intermediaries create costs, but they also perform functions. Banks, payment companies, custodians and clearing systems authenticate participants, safeguard assets, monitor suspicious activity, correct some errors, resolve disputes, maintain records and allocate losses when something goes wrong.

New technology may perform some of these functions differently. It may eliminate the need for others. Yet removing the institution does not automatically remove the underlying problem.

If a consumer sends funds to the wrong address, who can reverse the transaction? If a private key is stolen, who bears the loss? If an intermediary holds customer assets and fails, are those assets protected? If a blockchain becomes congested during market stress, how quickly can users reach redemption channels? If two technological systems disagree about the status of a transaction, which record has legal priority?

These questions are not peripheral. They determine whether an instrument can be relied upon as money outside controlled technical environments.

Regulation should therefore focus on functional protection rather than mechanically recreating every feature of the existing banking system.

Custody rules should address control and segregation of customer assets. Payment rules should define responsibilities when transactions fail. Operational resilience standards should require critical providers to prepare for outages and cyber incidents. Settlement rules should provide clarity about finality. Governance arrangements should establish who has authority to respond when exceptional conditions arise.

Innovation is most durable when users understand who is responsible for what.

A stablecoin transaction depends on the integrity of the entire operational chain—from wallet and network to custody, issuance, and reserve management.

VI. The Systemic Question: What Happens When Stablecoins Become Large?

An arrangement can be individually safe and still become systemically important.

This distinction becomes increasingly relevant as stablecoin adoption expands.

The first transmission channel is banking.

If households and businesses shift substantial balances from commercial-bank deposits into stablecoins, the immediate effect is a change in the composition of private money. The broader effect depends on what happens to the funds behind those stablecoins.

If reserves are placed largely in government securities or central-bank-like assets rather than recycled into commercial-bank funding, banks may need to replace deposits with other forms of financing. That could affect funding costs, balance-sheet structures and, over time, credit provision.

The magnitude of these effects remains uncertain and will depend on the scale and design of adoption. But the direction of the policy question is clear: sufficiently large stablecoins become part of the transmission mechanism between money, banks and credit.

The second channel runs through reserve markets.

Large issuers can become major holders of Treasury bills, government securities, repos, bank deposits and other short-term instruments. During normal periods, this may create an additional source of demand for safe assets.

During stress, the direction can reverse.

If redemptions rise rapidly, issuers may need to liquidate reserve assets. If several large issuers face pressure simultaneously, stablecoin runs could transmit selling pressure into markets that also play a central role in banking, collateral and monetary policy implementation.

The third channel is payment concentration.

A dominant stablecoin may become critical infrastructure even if its reserve assets are exceptionally safe. Millions of users and businesses could become dependent on its wallets, networks, interfaces and redemption system.

At that point, operational failure itself becomes a financial-stability concern.

This argues for proportionality. Regulation need not treat every small stablecoin as systemically important. Supervision should intensify as scale, interconnectedness and lack of substitutes increase.

The regulatory framework should therefore contain a credible path from ordinary oversight to enhanced systemic supervision.

Once stablecoins reach sufficient scale, redemption stress can spread beyond the issuer into safe-asset markets, bank funding, payment infrastructure, and broader financial stability.

VII. Competition, Monetary Sovereignty, and the Cross-Border Problem

Some of the strongest arguments for stablecoins arise in international payments.

Cross-border finance remains fragmented. Transfers can involve multiple correspondent banks, payment providers, compliance checks, foreign-exchange conversions and settlement systems. Costs can be high, particularly for smaller payments and less-developed corridors. Settlement can also be slow relative to domestic digital transactions.

Stablecoins can compress some of these processes.

A dollar-denominated token may move between digital wallets continuously, allowing firms to separate the transfer of value from some elements of traditional correspondent banking. Integration with programmable systems may further reduce reconciliation and settlement frictions.

These benefits also reveal the regulatory challenge.

A stablecoin issuer may be incorporated in one jurisdiction, maintain reserves in another, use technological infrastructure operated globally and serve users across dozens of countries.

Domestic licensing alone cannot fully address such a structure.

Differences in reserve requirements can encourage regulatory arbitrage. Inconsistent redemption standards can create unequal protection for holders. Divergent treatment of custody can make ownership rights uncertain. Cross-border transfers may complicate sanctions enforcement and anti-money-laundering controls.

For some economies, an additional question is monetary sovereignty.

The widespread use of foreign-currency stablecoins can make access to another country's currency easier and technologically more convenient. In economies with weak domestic currencies, limited banking infrastructure or recurring inflation, that may accelerate currency substitution.

This is not an entirely new economic phenomenon. Dollarization existed long before blockchains. Stablecoins can, however, reduce the technological and transactional barriers that previously limited its reach.

Policymakers therefore have to consider stablecoins within the broader architecture of international money, capital flows and payment dependence.

Effective oversight will increasingly require regulatory interoperability, information sharing and cross-border supervisory cooperation. A globally transferable instrument cannot be made fully resilient through isolated national rules.

VIII. A Better Regulatory Architecture: Regulate the Risks in Layers

A durable stablecoin framework can be built around five regulatory layers.

The first layer is the monetary claim.

This includes reserve quality, asset segregation, disclosure, redemption rights and treatment in insolvency. These requirements determine whether the promise of stable value is financially and legally credible.

The second layer is the issuer.

Issuers should have appropriate governance, internal controls, liquidity management, operational capability and risk-management systems. Capital requirements may also have a role, particularly for losses arising outside the reserve portfolio.

The third layer is infrastructure.

Wallets, custodians, settlement mechanisms, technology providers and other critical services create risks that cannot be solved through reserve regulation. Cybersecurity, operational continuity, asset protection and settlement finality belong here.

The fourth layer is activity.

A stablecoin used for retail payments does not create exactly the same risks as one used by professional investors for trading settlement. Distribution, payments, investment services, exchange activity and financial-market settlement may each require additional safeguards tailored to their function.

The fifth layer is the financial system.

Once a stablecoin reaches sufficient scale or interconnectedness, microprudential safeguards become insufficient. Stress testing, recovery planning, liquidity requirements, concentration monitoring and coordination with central banks and payment authorities may become necessary.

The value of this layered model is that it avoids choosing between two unsatisfactory extremes.

One extreme is regulatory exceptionalism: assuming that new technology makes established financial risks irrelevant.

The other is regulatory replication: requiring every new arrangement to reproduce the institutional structure of conventional banking before it can compete.

Neither approach is well suited to a period of rapid technological change.

A risk-based architecture allows regulation to become more demanding where economic risk accumulates while remaining relatively neutral regarding the technology used to provide the service.

That principle can support both safety and competition.

A durable stablecoin regime should regulate risks in layers—covering the monetary claim, the issuer, the infrastructure, the activity, and the system as a whole.

IX. What Decision-Makers Should Watch

For decision-makers outside financial regulation, the stablecoin debate can sometimes appear overly technical. The practical questions are considerably simpler.

The first is the nature of the claim.

When an organization accepts a stablecoin, holds one on its balance sheet, integrates it into a payment product, or uses it for settlement, it should understand what legal right ownership actually provides.

The second is the reserve structure.

What assets stand behind the tokens? Who holds them? How quickly can they be converted into cash? How concentrated are they? Are they protected if the issuer fails?

The third is redemption.

Who can redeem directly? How long does redemption take? Are there fees, minimum amounts or intermediary requirements? What happens during periods of market stress?

The fourth is operational responsibility.

Who controls custody? Which entities operate the wallets and payment interfaces? What happens if one of those entities fails? What recourse exists following fraud, theft or operational error?

The fifth is settlement.

At what point is a transfer legally final? Which jurisdiction's law applies? How are disputes handled when technological and legal records diverge?

The sixth is scale.

A structure that functions well at modest size may behave differently when it becomes embedded in large payment networks, financial markets or corporate treasury operations.

These questions matter to central banks and regulators, but they also matter to chief financial officers, corporate treasurers, banks, asset managers, payment firms, technology companies and investors.

The phrase “regulated stablecoin” can therefore provide less information than it appears to.

The more useful question is whether the full chain of monetary, legal, operational and systemic obligations is credible.

X. Conclusion: The Objective Is Trustworthy Digital Money

Stablecoins are part of a broader transformation in the architecture of money.

For much of modern financial history, several functions were bundled together inside banks and payment institutions. Deposit-taking, custody, payments, compliance, settlement and access to central-bank money were connected through a relatively concentrated institutional structure.

Digital finance makes it increasingly possible to separate these functions and recombine them in new ways.

A private company may issue the monetary claim. A regulated custodian may hold the reserves. A blockchain may record transfers. Independent wallet providers may distribute access. Financial institutions may provide redemption. Smart contracts may integrate the instrument into securities markets or commercial transactions.

That modularity is one of the sources of innovation. It is also the reason traditional regulatory boundaries are becoming less reliable.

The central regulatory objective should therefore remain anchored in economic function.

The monetary promise must be credible. The issuer must be capable of honoring it. Reserve assets must remain safe and liquid. Custody and payment infrastructure must remain resilient. Users must understand their rights. Activities should be regulated according to the risks they create. Systemic safeguards should become stronger as scale and interconnectedness increase.

Within those boundaries, technological competition should remain possible.

The long-term significance of stablecoins will depend less on whether they are described as cryptoassets, payment tokens, digital dollars or something else. What matters is whether they can provide the institutional qualities that society expects from money while delivering improvements that existing systems struggle to provide.

If those conditions can be established, stablecoins may evolve from instruments associated primarily with digital-asset markets into a useful component of modern payment and financial infrastructure.

If those conditions cannot be established, their technological efficiency will not compensate for weaknesses in trust, liquidity, governance or legal certainty.

The future of stablecoins will therefore be determined by more than technology.

It will depend on whether regulation can make the monetary promise reliable without preventing the infrastructure around it from continuing to evolve.
